DAY 1 Numerical Square: 98*98 = 97*97= 46*46= 34*34= 99*99= 94*94= 47*47= 41*41= 26*26= 11*11= 63*63= 72*72= 85*85= 54*54= Root: Ratio: 1)Are the ratios 3 to 4 and 6:8 equal?The ratios are equal if 3/4 = 6/8. These are equal if their cross products are equal; that is, if 3 x 8 = 4 x 6. Since both of these products equal 24, the answer is yes, the ratios are equal. 2)Solve for n: 1/2 = n/4. Using cross products we see that 2 x n = 1 x 4 =4, so 2n = 4. Dividing both sides by 2, n = 4 / 2 so that n = 2. 3)The ratio of 435 : 25 is same as a. 4 : 1 b. 2 :1 c. 7 : 5 d. 7 :10 A:a 4)The milk and water in two vessels A and B are in the ratio 4:3 and 2:3 respectively. In what ratio, the liquids be mixed in both the vessels so that the new liquid contains half milk and half water? a. 7:5 b. 1:2 c. 2:1 d. 6:5 A: a 5)The students in three classes are in the ratio of 2:3:5 if 40 students are increased in each class the ratio changes to 4:5:7 if 40 students are increased in each class...
